Steve Jobs thinks Objective C is Perfect?
josht writes "Nitesh Dhanjani has posted an e-mail thread between Steve Jobs and himself. Dhanjani argues "I'd like to see Apple developers gain more choice. With every iteration of OSX, there seems to be so much effort put into innovation of desktop components, but the development environment is age old." I agree with Dhanjani. What has Apple done recently to wow the developers, and make it fun to code Cocoa components? I've looked into the Objective C and Xcode environment but compared to Microsoft's .NET solutions, it doesn't impress me at all. I think Apple can do a lot better. Steve Jobs disagrees. What do the readers think about Objective C and Xcode?"
Anyone claiming a language lacking proper namespace support is "perfect" is nothing short of delusional.
He's already taken down the emails in question, apparently having had second thoughts about the appropriateness of posting private emails.
Sure, Xcode could do with a little bit of work to add features missing, but I truely find Cocoa a dream to work with. One year ago I only developed for the web, then I bought a Mac and was introduced to Cocoa by a friend. I havent looked back since, and have produced several 'scratch the itch' applications that otherwise wouldnt have been made.
The development environment is hardly static. Key-value-observing and bindings, Core Data; we get more toys for every system version and they are working on adding garbage collection to Objective C.
Network mirror still has the original blog post up.
Be a real patriot: Question authority. Think for yourself. Formulate your own conclusions.
Memory management in Obj-C is really simple, and making issue of it is an extreme exaggeration. You merely have to follow the rule of "if you allocate it, you're responsible for it", and make sure to either send it [obj autorelease] upon allocation or [obj release] in the [parent dealloc] routine. It really is that simple. Maybe that's too much to ask of the sissy programmers coming out of school these days.

You can accomplish the same things with inheritance
No, you can't.
If you add methods to a class with an Obj-C category, all instances of that class gain those methods. This is not the same thing as inheritance, where only instances of the subclass have the new capabilities.

Jeff Raskin was NOT the creator of the Mac. He was the originator (IIRC) of the Macintosh project, and its first manager, but his vision of the Macintosh was so at odds with Jobs', that to give Jef any credit for what the Macintosh became is unfair and incorrect. If you want to see Jeff's vision, go look at the Canon Cat, which he designed after being asked to leave teh Macintosh project.
Raskin was a smart guy, but he wanted to design interfaces for smart people; interfaces that had a learning curve associated with them due to all sorts of key combinations to remember. Though he backed away from this a little later in his life, when he saw how successful GUIs were (and, perhaps, wanting to claim an unfair amount of credit for that), all his interfaces were designed to be incredibly efficient for the intelligent geek who wanted to take the time to learn how to use them.
That doesn't really go along with the Mac's tagline "The computer for the rest of us."
Remember that history and fact are not the same thing. Jef & Steve both have (well, in Jef's case, had) their versions of what happened; neither is fact, and the real truth, if there is one, probably lies somewhere in the middle, probably a touch closer to Jobs' version, that is, if you know how to interpret the Jobsian language and make sure to read it outside of the RDF.
Well, Copeland and OpenDoc are pre-Jobs Apple, so go yell at Amelio or Sculley about those two.
On the rest of it, Apple never made a blanket "use Carbon", or "use Cocoa" claim. They said, consistently, to use Carbon if you have a lot of legacy toolbox code, and to use Cocoa if you were starting a project from scratch or were bringing things over from NextStep. OpenStep is just the old name for Cocoa and Rhapsody is just the old name for OS X, so you're kinda overstating your point just to make it look more schizophrenic than it really was.
Metrowerks was in it for the money just as much as anyone else; they weren't "there" for anybody but themselves (and later, their shareholders). Once Metrowerks released a Windows version, they stopped giving the Mac priority and the tools stagnated. Apple inherited a perfectly good IDE from NeXT and Metrowerks gave no indication that they were chomping at the bit to upgrade their tools in a urry so that developers could be ready when OS X came out. Metrowerks wanted to play it cautious and didn't want to gamble on Apple's transition to OS X, so what else was Apple to do? I've met relatively few people except a few cranky old Toolbox guys who didn't want to make the transition to OS X, who aren't happy with Apple Developer support compared with what it was historically. The Inside Macintosh books used to cost an arm and a leg and weren't available in soft editions, MPW was a nightmare, as you stated, and the only other way to create applications was to buy third party IDE.
Life has been pretty good (not perfect, but pretty good) since Apple bought NeXT. It's been tumultous at times, but has steadily been heading in the right direction, and as a matter of fact, developers have not been leaving the platform in droves; there has been a well-documented and steady increase in the number of developers using OS X as their primary platform.
I'd hardly say they're "suffering".
The interface can exist as separate code, though. All the stuff that IB serialises is available through the Cocoa API (check out the docs on NSView and NSControl, for example), and can be instantiated directly with programming statements if you wish. Using IB to keep the UI code separate from the stuff that interacts with it is however a better way to work, as it allows modifications to be to made the UI without having to recompile the application (separation of concerns).
MS recognise the above, and will themselves be following a similar route in the future with XAML, which is set to replace WinForms as the UI-building methodology of choice once Vista is launched (XAML will be one of the Vista technologies back-ported to XP). WinForms is thus in life-support mode at the moment: they will fix bugs, but not add more features to it because it is considered to be a deprecated technology.
NB: I've adopted a mixed-mode approach to Mac programming that seems to work very well from a productivity viewpoint. I do a lot of the main stuff in AppleScript or F-Script, and "drop down" to Objective-C for performance-critical stuff, custom Cocoa sub-classes, Darwin-related tasks, and other things that AppleScript or F-Script either isn't good at, or does too slowly. One could of course do this equally well using (for example) Python with the PyObjC bridge, and I believe that there is something similar for Ruby (don't quote me on that, though!), so the scripting languages I use are just one of the options available to Mac developers. And XCode happily manages all the different language files from a single project, ensuring that Obj-C code is compiled before running the interpreted stuff, managing CVS repositories, and generally making the experience pretty holistic.
I'm not going to change your sheets again, Mr. Hastings.
